[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 3 , Figure 4 The utility model provides an embodiment: a high-strength flame-retardant ABS trolley case, comprising two boxes 1, one side of the two boxes 1 is connected with a zipper strip 5, the outside of the zipper strip 5 is slidably connected with a zipper head 3, the front upper part of the front box 1 is rotatably connected with a front cover 10, the rear side of the front cover 10 is connected with a zipper strip 2 12, one side of the zipper strip 2 12 is connected to the front of the box 1, the outside of the zipper strip 2 12 is slidably connected with a zipper head 2 11, the two boxes 1 The front side and the left side are respectively fixedly connected with a combination lock 4, a rotating combination wheel 15 is rotatably connected to the upper side of one side of the combination lock 4, a screw slot 17 is provided on the lower side of the rotating combination wheel 15, a movable part 16 is slidably connected to the bottom side of the combination lock 4, an insertion rod 18 is fixedly connected to the upper front and rear of the movable part 16, the insertion rod 18 is slidably connected to the inside of one side of the zipper head 2 11 and the zipper head 1 3, a through slot 22 is provided inside the combination lock 4, and a fixed component is provided inside the through slot 22;

[0032] The fixing assembly includes a telescopic rod 21, which is arranged inside the through groove 22. Both ends of the telescopic rod 21 are fixedly connected with a block 19, and the block 19 is slidably connected to the inside of the insertion rod 18. The outside of the telescopic rod 21 is sleeved with a spring 20, and both ends of the spring 20 are fixedly connected to the corresponding sides of the two blocks 19.

[0033] By rotating the code wheel 15 to the correct number and pressing and pushing the movable part 16, it drives the insertion rod 18 to move and separate from the zipper head. When the insertion rod 18 moves, the card block 19 is squeezed. The shape of the card block 19 and the shape of the card slot opened in the insertion rod 18 are both trapezoidal, so that the insertion rod 18 moves to squeeze the card block 19, and at the same time, the telescopic rod 21 and the spring 20 are squeezed to separate from the insertion rod 18 and move to the inside of the through groove 22, so that the zipper head is released. When it needs to be fixed, the zipper head is placed in the slot 17 and the same operation is performed.

[0034] Reference Figure 1 , Figure 2 , Figure 5 The internal material of the box body 1 is provided with an ABS base layer 23 from the inside to the outside, a buffer softening layer 24 is provided on the outside of the ABS base layer 23, an anti-scratch thickening layer 25 is provided on the outside of the buffer softening layer 24, a moisture-proof layer 26 is provided on the outside of the anti-scratch thickening layer 25, and a fireproof layer 27 is provided on the outside of the moisture-proof layer 26. The four corners of one side of the two boxes 1 are fixedly connected with protective corners 7.

[0035] By using an ABS base layer 23, a buffer softening layer 24 and an anti-scratch thickened layer 25 as the material of the box body 1, the trolley case has the effects of being light and tough, resistant to compression, resistant to falling, fast rebounding from impact and wear-resistant. By using a moisture-proof layer 26 and a fire-proof layer 27, the trolley case has the effects of being moisture-proof and fire-proof. The protective corners 7 arranged around the box body 1 protect the external corners of the trolley case to avoid damage.

[0036] Reference Figure 1 , Figure 2 A telescopic pull rod 8 is arranged on the inner rear side of the rear box body 1; hooks 6 are fixedly connected to the left and right sides of the outer side of the rear box body 1, and a handle 9 is fixedly connected to the upper part of the rear box body 1; a storage cavity 14 is opened on the inner front side of the front box body 1, and four classification bags 13 are connected to the inner wall of the storage cavity 14; universal wheels 2 are fixedly connected to the left and right sides of the bottom of the two boxes 1.

[0037] The height of the telescopic pull rod 8 can be adjusted by pulling it up and down, so that it is easy to move. By setting the hook 6, the items in hand can be hung. When encountering stairs, the trolley case can be lifted up by the handle 9. Small items can be placed in the storage cavity 14 and placed in the classification bags 13 according to the actual size for storage. The trolley case can be moved by rotating the universal wheel 2.

[0038] Working principle: When the device is needed, the zipper head 1 3 and the zipper head 2 11 are pulled, so that the zipper strip 1 5 and the zipper strip 2 12 close the two boxes 1 and connect the front cover 10 with the front box 1 to protect the storage cavity 14. The movable part 16 is pressed and pushed to drive the insertion rod 18 to move, and the zipper head is placed in the slot 17. The movable part 16 is released, so that the insertion rod 18 moves and squeezes the card block 19, and at the same time squeezes the telescopic rod 21 and the spring 20. When the card slot on the insertion rod 18 is aligned with the insertion rod, the card slot on the insertion rod 18 is pressed. When 18 is aligned, the card block 19 is inserted into the card slot to fix it, thereby protecting the items inside the trolley case and preventing others from opening it and taking the items inside. The box body 1 is made of ABS base layer 23, buffer softening layer 24 and anti-scratch thickening layer 25, so it has the properties of lightness, toughness, compression resistance, drop resistance, rapid rebound after impact and wear resistance. The moisture-proof layer 26 and fire-proof layer 27 are set to have moisture-proof and fire-proof properties, so that the trolley case has high strength performance, is strong and durable, anti-collision and compression-resistant, rapid rebound, moisture-proof and fire-proof.
